在.NET CORE里面使用Consul注册和发现服务

1.NeGet添加 Consul 

2.添加consul

public static class ConsulRegister
{
public static void RegistConsul(this IConfiguration configuration)
{
#region 注册consul
string ip = configuration["ip"] ?? "Localhost";
//部署到不同服务器的时候不能写成127.0.0.1或者0.0.0.0,因为这是让服务消费者调用的地址
//int port = int.Parse(configuration["Consul:ServicePort"]);//服务端口
int port = string.IsNullOrWhiteSpace(configuration["port"]) ? 44344 : int.Parse(configuration["port"]);
ConsulClient client = new ConsulClient(obj =>
{
obj.Address = new Uri("http://127.0.0.1:8500");
obj.Datacenter = "dc1";
});
//向consul注册服务
Task<WriteResult> result = client.Agent.ServiceRegister(new AgentServiceRegistration()
{
ID = "apiserviceTest_" + Guid.NewGuid(),//服务编号，不能重复
Name = "apiserviceTest",//服务的名字--将来调用时用的就是这个
Address = ip,
Port = port,
Tags =new string[] { } ,//可以用来设置权重
Check = new AgentServiceCheck()
{
DeregisterCriticalServiceAfter = TimeSpan.FromSeconds(5),//服务停止多久后反注册
Interval = TimeSpan.FromSeconds(10),//健康检查时间间隔，或者称为心跳间隔
HTTP = $"http://{ip}:{port}/api/health",//健康检查地址,
Timeout = TimeSpan.FromSeconds(5)//超时
}
});
#endregion
}

}

3.在Startup注册Consul

 this.Configuration.RegistConsul();
